1. A genus of small marine protozoans with a spherical, chambered shell, commonly found in ocean sediments and used in paleoclimatic research.
Usage: scientific; typically used in plural form 'globigerinas' or as a mass noun; primarily used in geology, paleontology, and oceanography

Examples

• Globigerina shells accumulate on the ocean floor and form a significant component of deep-sea sediments.
• Scientists study globigerina fossils to reconstruct past ocean temperatures and climate conditions.
• The abundance of globigerina in sediment cores provides evidence of historical changes in ocean productivity.
• Globigerina ooze, a type of marine sediment, covers large areas of the Atlantic and Pacific ocean floors.
• Paleontologists use globigerina species to date and correlate rock layers across different regions.
